In Ahlburn v. Clark, 728 A.2d 449, 451 (R.I. 1999), the Court addressed the issue of standing as it applied to buyers and sellers of secular publications. 728 A.2d at 451. Ahlburn involved a statute that imposed a mandatory sales tax on bibles and other secular publications. See id. The court held that both sellers and buyers possessed "the requisite personal stake in the outcome of the controversy to satisfy the standing requirements." See id. at 452. The court found that the buyers faced economic injury if the sales tax was imposed and that the sellers could be held liable for failing to collect the sales tax. See id.
